Priority List

The List of Suggested Observations

The Priority List classifies the need to observe Near-Earth
Asteroids into four categories: urgent, necessary, useful and low priority.
This service focuses on newly discovered objects to ensure that the highest
possible percentage of these bodies can be recovered at other apparitions.

Near-Earth Asteroids (NEAs) observed at two or more oppositions,
but not numbered yet, will eventually be included when they show significant
ephemeris uncertainty.

Objects brighter than magnitude 22.0 V and at least 40
degrees of elongation from the sun are eligible for this list according to this
PLOT.
It is updated on a daily basis using data coming from
the Minor Planet Center and the NEODySdatabases.

Each category of this list is represented by an
abbreviation and the background color in the first column as indicated. For more
information read the "Explanation of Symbols".
